beaded or crossed by minute ridges, something after the manner in 
which the transverse sutures of certain Polydesmoidea are ornamented. 
The effect of these impressed striations is to give the body a peculiar 
satiny sheen. The striations do not appear on the dorsal surface of 
the first few segments, but come farther up gradually to about the 
tenth. 
Repugnatorial pores beginning on the fifth segment; located sub- 
dorsally and on the anterior part of the segments, so far in front that 
they are frequently concealed by the posterior edges of the adjoining 
segment. The pores are below the second seta from the middle, though 
the setz are near the posterior margin of the segment; the pores are 
usually just below one of the oblique lines which is then sinuate up- 
ward around the pores; sometimes the pore is midway between two 
lines which are then not sinuate, but are always wider apart than any 
other lines, for their whole length. ; 
Sete in four pairs; the lowest pair small and inconspicuous, but 
always present. 
Last segment rudimentary, with four setiferous conic processes. 
Anal valves not strongly convex, the margins not compressed or 
raised ; surface moderately hirsute with hairs of different lengths, espe- 
cially caudad. 
Preanal scale nearly semicircular, with the two sete usual in 
Diplopoda. 
Pleure striate in the same manner as the scuta. 
Pedigerous laminz of two sorts, those of the anterior pair of legs of 
each segment subtrapezoidal, those of the posterior pairs with the pos- 
terior corners produced. The spiracles are large and distinct. 
First pair of legs six-jointed in both sexes, the three distal joints 
fringed with long hairs. 
Second legs of male modified into hooks; four joints are distinguish- 
able, the two lower nearly coalesced. Second legs of female reduced, 
five-jointed, the joints fringed with long hairs, as are those of the first 
pair. 
Legs 3-5 of males distinctly crassate, the others slender. The 
distal joints of the anterior male legs have peculiar stout spines or 
chitinous processes in addition to the usual and ordinary hairs. 
Copulatory legs of male, see figures. 
Color a dark though bright, horn-brown; a narrow yellow median 
stripe; a row of light (whitish) spots in which the pores are located. 
The dark: color stops at the middle line of side, and below this the 
animal is colored a bright orange or light brownish-yellow; legs and
